摘 要:合成了两种有机染料,三芳胺染料XS51和二氢吲哚染料XS52,并分别用于钴基电解质和碘基电解质的染料敏化太阳能电池中.考察了染料结构对光物理性能、电化学性能和电池性能的影响.XS51为含有四个己氧基的三芳胺结构,表现出较好的空间位阻,从而提高了光电压.XS52中二氢吲哚的给电子能力强,从而短路电流较大.同碘电解质相比,所合成的染料更适合用于钴电解质的染料敏化电池中.在100mW/cm2的光强下,基于染料XS52的钻电解质太阳能电池总的光电转换效率达到6.58%.
Two organic dyes XSS1 and XS52 derivated from triarylamine and indoline are synthesized for dye-sensitized solar ceils (DSCs) employing cobalt and iodine redox shuttles. The effects of dye structure upon the photophysical, electro-chemical characteristics and cell perfor- mance are investigated. XS51 with four hexyloxyl groups on triarylamine performs better steric hindrance and an improvement of photovoltage. X852 provides higher short-circuit photocurrent density due to the strong electron-donating capability of indoline unit. The results from the redox electrolyte on cell performances indicate that the synthesized dyes are more suitable for tris(1,10-phenanthroline)cobalt(II/III) redox couple than I-/I3- redox couple in assembling DSCs. Application of X852 in the cobalt electrolyte yields a DSC with an overall power conversion efficiency of 6.58% under AM 1.5 (100 mW/cm2) irradiation.
